TRACGEN, an OpenTRAC KISS Frame Generator

To support
development of OpenTRAC hardware
and software I developed this little tool called "tracgen" which will
generate OpenTRAC position elements. The elements are generated from
an input file containing frames in TNC2 format. One could use a client
application or something like Afilter to generate such a file. The
OpenTRAC elements are encapsulated in AX.25 frames (with the OpenTRAC
PID of 0x77), converted into KISS frames and then made available on a
serial port of your choice, at the speed of your choice.

Tracgen is a Win32
application and has been tested on Windows 95 and Windows 2000. No
installation procedure is required other than unzipping the
tracgen.zip file into a directory of your choice. Run it from a command line
prompt (DOS box).

Currently, tracgen
will only convert position frames with and without timestamps,
including the compressed format. However, you do not need to edit the
input file in order to delete unsupported frames. It will simply only
parse the ones it can convert.

Tracgen requires 4
command line parameters. These are:

1) input_file
--> name of the file containg the TNC-2 type frames

2) serial_port --> a number from 1 to 4 indicating which comport you'd like to use
